Problems solved by technology

[0002] The workover rig is a kind of oilfield operation machine. It realizes its own walking and workover functions through the power switching device. When the workover rig is in the walking state, the engine power is transmitted to the front axle of the chassis through the transmission, transfer case and drive shaft. And the rear axle, before performing workover operations such as drilling and oil fishing, the operator needs to manipulate the power switching device to switch the engine power to the workover rig working device. When switching power, the operator needs to climb the frame of the workover rig On the narrow fixed table, it is very inconvenient to operate, and there are potential safety hazards

Abstract

The invention relates to the field of oil field operation auxiliary machinery, in particular to a well repair machine power switching device. The well repair machine power switching device comprises a supporting seat fixed to a middle cross beam of a frame and a support fixed to a left longitudinal beam of the frame, wherein a second transmission shaft is in rotatable connection with the supporting seat and is connected with a first transmission shaft through a coupler, the first transmission shaft is in rotatable connection with the support, the tail end of the support is connected with a handle, and two swing arms are arranged on the second transmission shaft and include a front swing arm and a rear swing arm. The well repair machine power switching device is simple in structure and stable and reliable in combination and separation actions during power switching, and an operator can perform power switching operation on the ground.

Description

technical field [0001] The invention relates to the field of oil field operation auxiliary machinery, in particular to a workover machine power switching device. Background technique [0002] The workover rig is a kind of oilfield operation machine. It realizes its own walking and workover functions through the power switching device. When the workover rig is in the walking state, the engine power is transmitted to the front axle of the chassis through the transmission, transfer case and drive shaft. And the rear axle, before performing workover operations such as drilling and oil fishing, the operator needs to manipulate the power switching device to switch the engine power to the workover rig working device. When switching power, the operator needs to climb the frame of the workover rig On the narrow fixed table, it is very inconvenient to operate like this, and there is a potential safety hazard.
